It’s really the air injection plumbing mostly. It runs under the engine to the passenger side. You can also remove the air pump in the driver side well next to the radiator. Good spot for an oil catch can when the air pump is out. I think Dominic (Xfirez51) is (or was) running the Dynomax resonator. Keep in mind stock pipes are 2.75” diameter, an unusual size. Most aftermarket exhaust items are either 2.5 or 3.0”s. Requires some adaptation. Unless your good at welding it’s best to let an exhaust shop do it. I’m a terrible welder. I usually cut all the pieces, fit everything together, spot weld it in place and let a shop do the final welding.
